Answer 1

Edit

Try declaring holder like this, and dont try to redeclare it later in the code.

final UserHolder holder = new UserHolder();

Final variables cant be reassigned

Answer 2

Use final UserHolder holder; instead of UserHolder holder = new UserHolder().

Answer 3

You cant access use local variables in this case, By the time the onClickListener is called the variables would have gone out of scope.

So instead you can set the ViewHolder as a tag for the button too, then you can access that in your onClick.

holder.btnEdit.setTag(holder);
holder.btnEdit.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
     ViewHolder tagHolder = (ViewHolder) v.getTag();

    // TODO Auto-generated method stub
    Log.i("Edit Button Clicked", "**********");
   /* Toast.makeText(context, "Edit button Clicked",
      Toast.LENGTH_LONG).show();*/

    int mValue = Integer.parseInt(tagHolder.textAddress.getText().toString());
    mValue--;
    if(mValue < 0)
    {
        System.out.println("not valid");
    }
    else
    {
        tagHolder.textAddress.setText( ""+mValue );
    }
   }
  });

I hope it helps!
